Currents of electric charges both generate a magnetic field and feel a force due to magnetic B-fields. All moving charged particles produce magnetic fields. Moving point charges, such as electrons, produce complicated but well known magnetic fields that depend on the charge, velocity, and acceleration of the particles. WebSep 12, 2024 · In a uniform magnetic field, a current-carrying loop of wire, such as a loop in a motor, experiences both forces and torques on the loop. Figure 11.6.1 shows a rectangular loop of wire that carries a current I and has sides of lengths a and b. The loop is in a uniform magnetic field: →B = Bˆj. The magnetic force on a straight current ...
